How should the FADPU be aligned?

The proper alignment of the FADPU (Fuel Aboard Discharge Pump Unit) is crucial for its efficient operation and safety. Aligning the FADPU by adjusting the pump discharge and suction pressure gauge isolation valves ensures that the flow of fuel is adequately managed and monitored. Proper pressure readings are essential for identifying any potential issues with the pump's operation, such as blockages or leaks.

When the isolation valves are correctly adjusted, they enable accurate pressure measurements that reflect real-time conditions within the system. This alignment allows personnel to make informed decisions regarding the operation of the pump, enhances system reliability, and contributes to the overall safety of fueling operations. Ensuring that pressure gauges are functioning correctly is fundamental to preventing accidents and maintaining system integrity.
